do you want to? ? cuz thts not good, but no. . . i dont. . . you asked. . . and m yanswer is no. . . we didnt have to say yes. . . iknow im smart. . lol :D

People who create them are aholes don't make one

Thank you all for down rating and being too cowardly to leave a comment or an answer. Excuse me for being curious. Thank you for being thought-crime police.

Yes. It's not very difficult to create one, although if you differentiate between trojans and viruses then it's difficult to find a reliable vector for one. Naturally, as others have pointed out, you wouldn't want to.

No and I don't want to know , its sad that people do that

Short answer: If you can write a program, you can write a virus. Long answer: Although I have not attempted to write a typical computer virus aka a program that does harm to a computer (beyond the practical joke on a friend), I suppose I could. There are even "virus writing kits" available for the kiddy haxors that can't do it themselves. Contrary to popular belief, not all viruses are written with the intent of harm or destruction. There have been several that do benign things such as spread, patch a security vulnerability, and then delete themselves. This could still arguably/potentially cause harm unintentionally (by crashing something or causing excess bandwidth usage etc...) but you get the idea. There are many types of "malware" and they all do different things so you should read up on them if you are interested. Some example types are: polymorphic, trojan, worm, backdoor, dialers... http://www.f-secure.com/glossary/eng/malware-code-glossary.shtml http://www.symantec.com/business/security_response/threatexplorer/risks/index.jsp The whole hacker underground and botnets would probably be of interest to you as well. Currently, there is a botnet (hundreds of thousands of "commandeered" home computers similar to the one you're using right now all working together to perform a DDOS attack, or send spam, or just doing nothing other than maintaining their own healthy network) that has more processing power than any of the known supercomputers on earth. A lot of security experts are crapping their pants because they are not sure if and/or when it will be used by its "owners" to do something really bad. (so far it hasn't done much of anything) It uses the peer to peer overnet protocol which is encrypted and pretty much headless so it is next to impossible to track down who is controlling/using it. http://www.usenix.org/event/hotbots07/tech/full_papers/grizzard/grizzard_html/ I hope this is useful to you. I would strongly discourage any virus writing. Even if you wanted to create a test environment just on your personal network or something, it could easily get away from you. It has happened to professors and some pretty smart people in the past. Some did jail time for it... Cartoon courtesy of: xkcd http://xkcd.com/350/

Push the wrong button!!

look for the weaknesses in a software and abuse it. But the Feds, Microsoft and about 1 billion people throughout the world will learn to hate you

I created one once when I just started out learning programing. It was just for fun. It basically just opened the calculator in Windows a thousand times. It cause the computer to freeze up. Once I restarted the computer I just got rid of the program.

I created one too, by accident, when I was fairly new to programming. I created a small process that creates copies of itself, and the child processes seek out and destroy the parent process. Within a few moments there were thousands of runaway copies, and they couldn't be removed because they kept getting killed before you could find them. The computer (a shared supercomputer) had to be shut down because of it :(

Yes, but smart people don't create virii. They complain about the people who do.

Yes probably into the hundreds if you counted every variation as different. Not left my network thought, eduactional reasons. If you know nothing of programming, start by creating batch files. I have thousands of examples if you would like to learn to make simple programs that aid productivity.
